Talus Talus. an accumulation of rock fragments at the base and on the lower part of a steep mountain slope. Talus forms when rock weathers and fragments roll down a slope. The material is un-sorted and usually consists of angular fragments varying in size from sand grains and chippings to blocks several meters across.

- The Softest Mineral in the World: Mineralogy and Geology. Talc is a platy mineral belonging to the group of silicates. It is formed either through regional or contact metamorphosis of carbonate sediments or through hydrothermal alteration of magnesium-rich magmatic rocks.

Leukoplakia â Symptoms, Causes, Treatment, Pictures Leukoplakia Causes. Reasons for leukoplakia are dependent on what type of leukoplakia – standard or hairy. Standard Leukoplakia. While the cause of leukoplakia is not known, the use of tobacco, including chewing and smoking, seems to be accountable for the majority of cases. 3 out of 4 users of tobacco products regularly will in due course cultivate leukoplakia in the area where the tobacco is held against the cheeks.

Talus Talus. The talus is an important bone of the ankle joint that is located between the calcaneus (heel bone) and the fibula and tibia in the lower leg.

Anatomy The talus is the bone that makes up the lower part of the ankle joint (the tibia and fibula bones of the lower leg make up the upper part of the ankle joint). The talus sits above the heel bone (calcaneus).ecause the talus is important for ankle movement, a fracture often results in significant loss of motion and function. In addition, a talus fracture that does not heal properly can lead to serious complications, including chronic pain. For this reason, many talus fractures require surgery.

- The talus is an important bone of the ankle joint that is located between the calcaneus (heel bone) and the fibula and tibia in the lower leg. The shape of the bone is irregular, somewhat comparable to a turtle's hump.

- Talus: small bone that rests between the heel bone and the tibia and fibula. The MOR foot and ankle specialists classify ankle fractures based on the area of the bone that is broken. Fractures are classified by the name of the bone that is fractured or the number bones fractured if there is more than one.alus: small bone that rests between the heel bone and the tibia and fibula.

- Talus bone. The talus (/ˈteɪləs/; Latin for ankle), talus bone, astragalus /əˈstræɡələs/, or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint through its articulations with the lateral and medial malleoli of the two bones of the lower leg, the tibia and fibula.

Medical Definition of Talc Medical Definition of Talc. Talc: A very soft, soapy-feeling mineral that is a silicate of magnesium, sometimes with small amounts of aluminum silicate. Talc is used in making dusting powder (talcum powder), in cosmetic preparations, and as a filter aid in pharmacy. The inhalation of talc can lead to a chronic lung disease called talcosis which is related to silicosis. It occurs in workers exposed to talc mixed with silicates.

- The Buchan Facies Series of regional metamorphism is characterized by the presence of andalusite, and sometimes cordierite, in intermediate grade mineral assemblages indicating that the conditions of metamorphism were at lower pressure and along a higher metamorphic field gradient than that recorded in Barrovian Facies Series metamorphic rocks .

- Because of this, the study of such material is often known as Quaternary geology, after the recent Quaternary Period. This includes the study of sediment and soils, including studies in geomorphology, sedimentology, and paleoclimatology.

Scree Scree is a collection of broken rock fragments at the base of crags, mountain cliffs, volcanoes or valley shoulders that has accumulated through periodic rockfall from adjacent cliff faces. Landforms associated with these materials are often called talus deposits.

Talus Fracture of the Ankle Signs of a Talus Fracture. Patients who have a talus fracture have significant ankle pain, difficulty bearing weight on the ankle, and swelling around the ankle joint. Patients should have immediate x-ray evaluation to determine if there is a talus fracture, or any other injury around the ankle.

Talar Dome Lesion A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). “Osteo” means bone and “chondral” refers to cartilage.

gneiss gneiss (nīs), coarse-grained, imperfectly foliated, or layered, metamorphic rock rock, aggregation of solid matter composed of one or more of the minerals forming the earth's crust. The scientific study of rocks is called petrology. Rocks are commonly divided, according to their origin, into three major classes—igneous, sedimentary, and metamorphic.

Talc Talc is a metamorphic mineral resulting from the metamorphism of magnesian minerals such as serpentine, pyroxene, amphibole, olivine, in the presence of carbon dioxide and water.This is known as talc carbonation or steatization and produces a suite of rocks known as talc carbonates.alc is used in baby powder, an astringent powder used for preventing rashes on the area covered by a diaper. It is also often used in basketball to keep a player's hands dry.

- Talus, or scree, is the loose rock created by physical weathering. It typically lies on a steep mountainside or at the base of a cliff.(more below). If you're writing a geologic paper, talus is the preferred term, but scree is more fun to say. This example is near Hoefn, Höfn. icelandalus, or scree, is the loose rock created by physical weathering. It typically lies on a steep mountainside or at the base of a cliff. (more below).

- This is common in basaltic rocks that generally lack hydrous minerals. The hydrothermal metamorphism results in alteration to such Mg-Fe rich hydrous minerals as talc, chlorite, serpentine, actinolite, tremolite, zeolites, and clay minerals.
